Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491598, here are decompositions:

5 + 491593 = 491598
7 + 491591 = 491598
17 + 491581 = 491598
59 + 491539 = 491598
61 + 491537 = 491598
67 + 491531 = 491598
71 + 491527 = 491598
97 + 491501 = 491598

Showing the first eight; more decompositions exist.
